Effects of Inoculation with Three Arbuscular Mycorrhizal Fungal on the Growth of Peach Palm Seedlings

  • Received Date: 2006-04-28
  • Peach palm seedlings coming from seeds of San Carlos provenance and family 14152 of Costa Rica were cultivated at a nursery in South China.A experiment by employing randomized block design with the two progenies was undertaken to test the infection rate and inoculation efficacy by artificially inoculated with three arbuscular mychorrhizal fungus(AFM): Glomus versiforme,G.caledonium and G.manihotis.Results indicated that the three AMF treatments were capable of colonizing root system of the two progenies'seedlings to form ectomycorrhizal association after inoculation.The infection rate was 26.7%~50.0%,infection index 13.3~37.5.There was no evident effect on the above growth of the two progenies 7 months after inoculation even though infected.However,a positive response of the growth in root system of family 14152 of San Carlos provenance was identified after inoculation(P<0.05).Compared with un-inoculated treatment(the control),the below-ground biomass and the length of main root of 14152 inoculated with isolate of G.manihotis,G3008,was enhanced by 80.0% and 51.4% respectively.G3008 isolate was the most efficient colonizer among the tested three isolates for root growth of seedlings of 14152 of San Carlos provenance.
